WOOD-GRAINER.

Application filed March '28, 1921. Serial'No. 456,404.

To all whom iii may concern Be it known that I, EDWARD J OLLIFFE, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Wood-Grainers, of which the following is a specification.

My invention relates to improvements in Wood grainers, and has for its main object the provision of an improved machine for producing graining and similar ornamentation on wood surfaces.

Another object is to provide a grainer having a main and an auxiliary graining member.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a plan view of my improved machine Fig.2 isa side view thereof; and v Fig. 3 is a fragmentary view showing the idler or smaller roller extended. I

The construction shown comprises a frame composed of side members or plates 10 conneeted by spacing rods 11 which are positioned between the upper and lower edges of said plates. A roller 12 is rotatably mounted upon shaft members 13 at one end of said frame and a roller 14, covered with layers of rubber 15 and felt 16, is mounted on shaft members 17 at the other end of said frame, the surface of said roller extending beyond the confines of the frame. Said cushioning layers of rubber and felt make the roller pliable and suited to effect a clear design on an uneven surface. The roller 12 may be similarly covered with rubber and felt.

An endless belt 18, which is made of some suitable material, as rubber, operates over said rollers and has the required design shaped upon its surface in the form of depressions and elevations.

Ain idler 19 is rotatably mounted by means of shaft members 20 on the outer ends of arms 21 provided with slots 22 near their inner ends through which extend pivot bolts Springs 24 are mounted in notches .25

and engage pins 26 provided on the side plates, bearing with their outer ends against the inner ends of arms 21. Said springs serve to seat shaft members 20in slots 27 on the frameand to press the idler down upon the belt to keep it taut as shown in Figs. 1 and 2. i V

The idler is provided with a suitable covering 28 such as rubber and has the desired design formed upon its surface in a similar manner as the endless belt, but the design being of a different and preferably a coarser grain. Said idler. maybe swung outward upon its arms 21 as shown in Fig. ,3, catch ing the notches 29 of said arms over shaft members 17 and pressing the arms inward over said members until the slotted ends 30 of said notches engage said members.) The springs 24 bear against said arms to assist in retaining them in position. Since the idler is provided with a design differing from that of the belt, it may be used to grain the trimmings or the special frame work while the endless belt is used to grain the main woodwork. H I .1

Hand .plates 31 areprovided on the frame near the small roller 12.

In use, the operatorgrasps the grainer by the handpla'tes 31 bringing the end with the extended roller 1 in contact with the woodwork and rolls the belt over the Surface which "contains a fresh coat of graining material newly applied over a sub-coat previously hardened and usually of a darker color. The elevations on the'belt will thus remove a portion of the freshly applied outer coat of graining material, thereby exposing the lighter sub-coat. The idler may be swung out as shown in Fig. 3 and used in a similar manner.

My device, above described, varies from the usual graining machines which apply a graining coat to wood surfaces from a liquid container carried on the machine in connection with the graining belt.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations a frame, an idler pivoted on said arms, and

resilient means mounted on said frame and pressing against the ends of said arms to keep' the belt taut by means ofsaid idler.

,2. A graining device comprising a frame, an endless belttraveling on rollersinountedL in said frame, means pivoted on said frame, a rotary member carried by said means,'a graining design formed around saidrotary member, and mounting means for said pivoted means to use said rotary member either as abelt tighter ora Wood graine'r.

3. Agraining device. comprising a frame,

an endless graining belt traveling on rollers pivoted on said frame, arms pivoted on said frame, a rotary graining member carried by said arms, notches and slots in said arms, and pinsextending from said frame to en gage insaid notches and slots to adapt said rota'rymember as an auxiliary graining member.

4. A graining device comprising a frame,

rollers mounted in said frame, an endless 'graining belt passing over said rollers, arms pivotedon said frame, a "rotary graining member pivoted on sald arms, means on said arms to engage pins on said frame to. hold thearms and rotary member extended as an auxiliary-graineiyand spring means 'to engage said arms and press the rotary ember on the belt and also to retain the arms in their extended posit on.

5. A graining device compr sing a frame,

rollers mounted at the end of said frame,

an-endless graining belt passing over said rollers, one of'said rollers being'provided With a rubber 'and felt cushioned periphery extending beyond said frame, an idler mountedon said frame, and resilient means tween the outer ends of said arms, and

means to retain said idler andarmsineither a belt-engaging or an extended position.

' 7. Agraining device comprising a frame, rollers mounted in said f'ame, an endless belt traveling over said rollers, one of said rollers being provided With a Cushioned peg riphery of rubber and felt extending. beyond said frame, arms swingably mounted on said frame, an idler rotatably mounted between the outer ends of said arms, andmeans engaging said arms to retain said idler and arms in either a belt-engaging or an extend} ed position, V p 7 8." A graming device comprisinga frame,

an endless graining belt traveling onrollers pivoted on said frame, arms' mounted on said frame, .a' rotary graining member carried by said arms and havinga graining design differing from that on the belt, and means to retain said arms and rotary member in extended position as an auxiliary 'graining member,"

9. A graining device comprising'a frame, an endless graining belt traveling on. rollers pivoted .on said frame, arms swingably mounted on said frame, a rotary graining member carried by said arms and having'a graining design differing from .thato'n, the belt,'and means engaging said arms toretain the arms and rotary member in either a beltengaging' position or in an extended position as an auxiliary graining member.
